The 40 mm shaft height places this motor at the lower end of the 1FL2 frame family; it pairs with the SINAMICS S200 drive line as a matched set, so commissioning engineers plug straight into the drive's motor table without having to manually enter encoder and winding parameters. ## Mechanical and feedback package for the wiring bench Feedback is the AS17 bit absolute single-turn encoder delivered through a hybrid connector — a single-cable solution that carries both power and the encoder signals on one moulded cordset, so the cabinet-side wiring drops to one hybrid plug per motor instead of separate power and resolver/encoder runs. The shaft is supplied with a shaft key and tolerance class N, and the motor is built without a holding brake — if the axis needs to hold position with the drive powered down, a brake-equipped variant from the same family must be specified instead, because retrofitting a brake on a non-braked frame is not an option. Protection class is IP54 without an oil seal — adequate for general industrial cabinet interiors and clean machine rooms, but not for wet-side food-and-beverage washdown or for gearboxes that weep oil past the shaft entrance; if the motor bolts directly to a reducer or sits in a splash zone, the application needs an IP65 or oil-sealed variant of the family. ## Production status and what \"made to order\" means for the BOM The product class is recorded as C — products manufactured or produced to order that cannot be reused, re-utilised, or returned against credit, which means the order is built once the PO lands and a cancellation or rework request would not be entertained; plan the BOM lead time accordingly and only release the line when the spindle count is firm. Compliance with the RoHS substance restrictions is recorded as in effect since 01-01-18, and REACH Article 33 duty-to-inform applies per the current candidate list — meaning the reach declaration has to travel with the part into the EU rather than being held back at the manufacturer.","metaTitle":"Siemens 1FL2104-4AF00-1HC0 Servo Motor, 1 kW, 3000 rpm","metaDescription":"Siemens 1FL2104-4AF00-1HC0 SIMOTICS 1FL2 servo motor, 400 V 3AC, Pn 1 kW, Nn 3000 rpm, 3.2 Nm, IP54.
